I consider it conservative, not maintenance but maybe either or. I doubt they are full grown, more slow grown. Neither is over four feet and right about 7.5# according to me holding them standing on a scale lol. I think the majority of snakes are vastly overfed and with their slow metabolism and low activity level, that there's no reason to offer larger prey or more often. You can't tell obesity level by outside appearance until they are ungodly fat.
